The addresses we hold

Where the letter goesMailing address
SumoCecil Street 411033006 SouthbankAustraliaThe Australia address on file for Sumo. Postal code 3006.
How to address the envelope
Copy it exactly onto the envelope
Write out Cecil Street 41, 103, 3006 Southbank, Australia as shown above, including the 3006 postal code, exactly as printed.
Add your return address
Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.
Certified mail, not a courier
Ask at the counter for the certified service with a return receipt: the fee is on top of the postage, the receipt is postmarked, and the article number traces the delivery.
Keep the records
Keep your copy of the letter, the receipt and the delivery record in one place. The delivery date is the one to quote if the account is billed again.

The letter below asks Sumo to end the account, stop further charges and confirm in writing. Put the name and email on the account and, if you have one, an account or customer number in the bracketed places.
